The basic motion elements Edit The standard symbols used in representing the 18 therbligs. A basic motion element is one of a set of fundamental motions required for a worker to perform a manual operation or task. The set consists of 18 elements, each describing a standardized activity. Transport empty [unloaded] TE : receiving an object with an empty hand.

Together, with his wife Lillian Moller Gilbreth were experts in the efficiency of work, they stood out for giving great contributions to the study of movements and human factors. Frank Gilbreth did not do formal education beyond high school. At that time, he also worked as a professor at Purdue University. Frank Gilbreth found out his vocation while working as a contractor, as he began to think of easier and more efficient ways of structuring the bricks for construction.
The previous analyzes resulted in the formal study he did with his wife, which was related to habits in the manufacturing and office work in all types of industries. The goal of theses studies was to find ways to increase profits and do the work easier. In addition, he and his wife created the consulting firm, Gilbreth Inc. In this project, Gilbreth, applied the time and movement theory for construction with bricks and transportation was applied.
His job was to find faster and more efficient ways to arm and disarm weapons. Consequently, in the first years of the twentieth century, he and his wife, in search of a more efficient method to develop manual tasks, developed a classification of 17 movements with which any work activity can be subdivided to analyze the motor productivity of a worker in their job.
They stated that once the worker is assigned a task, it can be divided into the necessary therbligs so that it is done with success. The therbligs also classified two groups: the efficient ones, that manage to add value to a task, and the inefficient ones that generate costs. After finishing the study of movements, Frank Gilbreth and Lillian Moller found that the strategy to improve work efficiency was to reduce unnecessary movements that caused fatigue to employees.
Their work to reduce fatigue was based on the reduction of movements, redesign tools and the height at which some pieces were located. Besides the movements research, Gilbreth and his wife developed the personnel card system used in the current merit rating systems. In addition, they emphasized in the written instructions to avoid confusion, considered as the most outstanding disciples of Taylor, they used techniques of scientific management to reduce the waste of manual and bodily movements at work.
Also, they conducted experiments on the design and use of machines and correct tools to optimize the performance in work. Frank Gilbreth died on June 14, , at the age of 55, due to a heart attack while talking on the phone at the Lackawanna train station in Montclair, New Jersey.

Frank y Lillian Gilbreth inventaron y refinaron este sistema, aproximadamente entre y ver Los esposos Gilbreth. Como dijo Frank Gilbreth: " Encontrar Si hay un enigma en el sistema Therblig, entonces ese es el de Encontrar. El Dr. Se ha dejado ya que en otras aplicaciones puede ser utilizado. Si bien puedes contar cada bolsa 1 a ,o puede ahorrar una gran cantidad de tiempo teniendo una balanza precisa y encontrando el peso promedio de una bolsa de clavos.
